A fatal error means a non-recoverable error in a program or operating system that immediately causes the system or software to stop working, often called a crash. When this happens, all of your software processes will be hampered, and you may even lose the unsaved data. The same goes for QuickBooks: it may close unexpectedly or keep crashing each time you open it.

But the good news is that you can resolve the QuickBooks fatal error by identifying the root causes and specific troubleshooting steps, such as updating the software, Windows, and more. Let’s walk you through this guide and see what you can do to fix the fatal error in QuickBooks Desktop.

Top 9 Ways to Resolve the Fatal Error in QuickBooks Desktop

Here are the troubleshooting steps to help you resolve the root causes of the fatal error in QuickBooks Desktop. Please follow these fixes carefully:

1. Restart your computer

Restarting your computer clears background processes or other temporary conflicts that may be interfering with the program’s normal operation. It also refreshes software connections and resets permissions, giving QuickBooks a fresh start without any conflicting elements that may be causing the error.

2. Update QuickBooks Desktop

Updating QuickBooks Desktop, make sure you use the recent software features, bug fixes, security patches, and that the software is compatible with Windows OS. This will resolve the conflicts caused by outdated Windows and ensure the fatal error is resolved.

3. Update Windows

Incompatibility of Windows components with QuickBooks Desktop can cause a QuickBooks Fatal error. Update the operating system using the steps below to resolve the issue.

  • Launch the Windows Start menu.
  • In the search field, type Settings and press the Enter key.
  • Select Windows Update in the left menu bar.
Windows update
  • Hit on Check for Windows updates.
  • If you see the updates are available, choose Download & Install.
  • Once done, restart your computer to apply the updates.

4. Repair the hard drive

  • Launch the Windows File Explorer and select This PC.
  • Right-click on the drive containning Windows OS (usually C:) and click on Properties.

scan drive
  • Once CHKDSK is finished, select Show Details to check the errors that are resolved, or simply click Close to close the window.

5. Rename QBWUSER.INI file

Renaming the QBWUSER.INI file may resolve the possible damages or missing data. Let’s learn how you can rename this file:

Note: Renaming the QBWUSER.INI file removes the list of your previously opened company files. You’ll need to manually reopen your company file.

To rename the file:

  • Locate the folder where the QBWUSER.ini file is saved. The default location is: Users[Your user name]AppDataLocalIntuitQuickBooks [year]
  • If you can’t find the folder, enable the hidden files and folders.
  • Right-click on the QBWUSER.ini file and select Rename.
  • Add .OLD at the end of the fila name such as QBWUSER.ini.old.
  • Name the EntitlementDataStore.ecml file again.
  • Try to open QuickBooks Desktop.

If renaming either the QBWUSER.ini or EntitlementDataStore.ecml file allows the program to open, try accessing a sample company file.

If the sample file opens but your company file doesn’t, move your file to a different folder and open it from there. (It’s best to use a local folder, not a network location.) If it opens, the issue could be a damaged folder or folder permissions.

If the file still won’t open, it’s likely damaged. In that case, restore an earlier backup of the file.

If you can’t open the sample company file or QuickBooks won’t launch, the installation may be corrupted. In that case, follow the steps in Solution 9, and try deleting the entitlement file.

6. Delete the entitlement data store file

The entitlement file stores product and license information for QuickBooks Desktop and verifies QuickBooks that the product is valid and activated. If the file is corrupted, you must repair following the below steps:

  • Press the Windows Start menu.
  • Type Run into the Windows search and press Enter.
  • In the Run prompt, type C:\ProgramData\Intuit\Entitlement Client\v8 and then Enter. If the QuickBooks folder does not open, type C:\ProgramData\Intuit\Entitlement Client\v6 instead. Note: If you still can’t find the V6 or V8 folder, open Windows file explorer and go to C:, ProgramData, Intuit, and then Entitlement Client. Make sure Hidden items is checked in file explorer.
  • Look for the EntitlementDataStore.ecml.
  • Right-click on same file and select Delete, then click Yes to confirm.
  • Open QuickBooks and your company file.
  • Follow the steps on your screen to register QuickBooks again.

7. Run the SFC scan

The System File Checker (SFC) is a built-in Windows tool that checks and repairs corrupted system files, helping fix problems that may prevent Windows from functioning properly.

  • Press the Windows + X keys on your keyboard.
  • From the Quick Link menu, select Command Prompt (Admin). NOTE: You can also run SFC from Windows PowerShell (Admin).
  • Click Yes on the User Account Control (UAC) prompt.
  • In the command prompt window, type SFC /scannow and hit Enter.
sfc scannow
  • The System File Checker will scan and repair any detected issues with Windows system files.
